Abstract
BACKGROUND: Liver involvement in dengue illness is common and can lead to acute liver failure (ALF). No single method can effectively identify patients at risk for disease progression and bad outcome. We aimed to determine the relationship between liver dysfunction, kinetics of liver function tests (LFTs) and severity of hepatitis on the outcome in pediatric dengue illness. METHODS: We conducted a prospective observational study of hospitalized children (1-12 years) with dengue infection (July 2014-July 2015). Serial monitoring of LFTs was done in confirmed dengue cases. Patients were classified into non-severe (NSD) and severe dengue (SD). Severity of hepatitis was graded: mild, moderate and severe hepatitis. Events were noted during hospitalization. RESULTS: One hundred two children (66, boys), median age 72 (48-96) months, were analyzed (NSD, n = 41; SD, n = 61). Elevated transaminases (92%) was the most common abnormality; aspartate transaminase (AST) and alanine transaminase (ALT) in 87% and 82%, respectively. Maximum abnormalities in LFTs peaked at day 5 (AST, ALT) and day 7 (Alkaline Phosphatase [ALP], gamma-glutamyl transferase) of illness. Elevated transaminases was found to be higher in SD than NSD (100% vs. 80%, P = 0.006). Severe hepatitis developed organ dysfunction such as altered sensorium (P < 0.001), ALF (P < 0.001), acute kidney injury (P < 0.001) and shock (P < 0.001), more commonly than those with mild to moderate hepatitis. Fourteen patients died, two-thirds of whom had severe hepatitis (P < 0.001). Using binary logistic regression, presence of severe hepatitis and shock at presentation was an independent predictor for ALF (odds ratio: 77; 95% confidence interval : 13-457, P < 0.001) and mortality (odds ratio: 55; 95% confidence interval: 4.6-66, P < 0.001), respectively. CONCLUSIONS: Many children with dengue have liver involvement. Severe hepatitis in dengue is associated with significant organ dysfunction and poor outcome.
